Answer

The major intestinal complications of Crohn disease are due to the transmural nature of the disease, which leads to the formation of abscesses, fistulae, sinus tracts (incomplete fistulae ending in a cul-de-sac), strictures, and adhesions. These features may also contribute to bowel obstruction.
